IMPROVEMENT IN' MACHINES FOR FULLING CLOTH.

m The Schedule referred to in these Letters Patentand making part o the same.

To all persons totwhom Athese presents may come;

Be it known that I, RODNEY HUNT, of Orange, of the county of Franklin, of the State of Massachusetts,

have invented a new and useful Improvement in Ma-4 chinery for Fulling Cloth; and do hereby declare the same to be fully described as follows, reference being had to the accompanying drawing, of which- Figure 1 is a vertical and longitudinal section of a fnlling-machine containing myimprovement, the said section being taken between a pair of its vertical rollers.

Figure 2 isa rear elevation of the machine, with its doors open.

Figure 3 is a side view of it. A l The machine is somewhat analogous to those` described in the United States Letters Patent, 3,605 and 87,806. In this machine the packingfcouduit or conduits, used in machines covered by such patents, are dispensed with, as the improvement which I have hereinatter described enables vthis to be done, the said improvement consisting in the substitution ot' horizontal tinted rollers in the place of plain or non-tinted rollers, in combination with one or more pairs of plain or vertical luted main rollers.

In the machine represented in the patent No. 87,- 806 vertical crimping-rollers or gears are used, with plain main horizontal or squeeze-rollers and a packingconduit, it having been found -that the employment of vertical crimping-rollers instead of plain ones, with the packing-conduit, was productive of advantages. "By such rollers the cloth, while passing between them, was corrugated or crimped, and, consequently, was not only packed to better advantage in the conduit, but was better or quicker fulled.

I have discovered that, by tiuting the main or horizontal rollers, and employing, in connection with them, one or more pairs of vertical rollers,`e ither plain or flutcd, and especially when they are uted, the packirrg-conduit or conduits may be dispensed with, and the fulling of the cloth be eifected to great advantage by the conjoint operations of such rollers.

In'the drawing- Y A and B denote the main squeeze-rollers, whose periphenes are tinted, the utes running transversely y thereof, or parallel to their axes. These rollers are arranged within the case E, one of them being disposed directly over the other, and both'having their-axes horizontal.

A. driving-pulley, C, as well as a loose pulley, C', is arranged on the shaft of the lower roller B, wheresuch shaft projects beyond the -case E. The supportingframe of the case is shown at D.

1Directly in rear of the uted rollers A B are one or two sets of crimping-gears or rollers, F G, whose axes are disposed vertically. The shaft of one roller of each vertical pair is sustained at its upper end in a rod, a, which is led through one sideof the case, and through asprng, or prism, or cylinder, b, of India rubber, arranged against the' outer side of the case'. The rod a terminates in a head or nut, c, to bear against the outer end of the spring.

Furthermore, each journal'of the upper main or horizontal uted roller rests against a saddle, d, forced against the journal by a spring or mass of India rubber, c, (see lig 8,) in which the journal is shown at f as resting on'its box g, and having the saddle and spring arranged as therein shown.

In rear of the two sets of crimping-rollers F Gr` is a horizontal guide-roller, H.

In advance ofthe two rollers A B are one or more curved passages K, as in the patented machincs'hereinbefore mentioned.

In using my machine, a piece of cloth to be fulled is first led over the guide-roller H; and between a pair of the vertical rollers F G, and thence between the pair of uted horizontal rollers A B,-theuce into and down the passage K. Finally, the two ends of the piece are .to be sewedor connected together.

This having been accomplished, and the soap-cisterns I, at the sides of the machine, having been-supplied with liquid soap, such as usually employed in fulling-mills, the lower main roller should be put in revolution, in which case each of the pieces of cloth will be'drawn forward between its pair of vertical rollers, and, after having been crimped by the conjoint `action of the horizontal rollers, or such and the vertical ones, will be forced into and down the passage K. The continued operations of the roller,A and the running of the piece of cloth the necessary number of times between them will effect the fulling of it.

When' the vertical and horizontal sets of rollers are tinted, the piece of cloth will be crimped or corrugated in two directions, at right angles,and'will be much l better and sooner fulled than would be the case were l the rear or vertical rollers plain or non-tinted.

It has been found, when the main or horizontal rollers are flnted, that. theycause the cloth not only to full better, but to fold, or lay in folds, to greater ad' vantage in the passage K.

When the packing-conduit, as described in the aforc said patents, is used with tinted vertical rollers and plain main rollers, the latter. operate to remove the corrugatins produced by the rear vertical rollers, and also to crowd the cloth into and through the paclringconduit, out of which it falls much compacted, and, in this state, enters and goes through the liquor.

With the main rollers fluted, the cloth will be de' livered-corrugatcd transversely, whereas it wlll readily fold so as to enable the liquor to penetrate it to the best advantage. Thus, it will be seen that the employment of tinted main rollers, in connection with the upright rollers, eitherv plain or tinted, has positive ad vantages, or vis Aproductive of new or better results.

2 o ,os I herein make no claim to any thing, arrangement, the first, whereby a much better and more speedy fullor combination of parts, as described, in either of the ing of lit lwill be effected.

patents hereinbefore mentioned. j By luting the main squeeze-rollers A B, and by ar- I am aware of the British patent No. 3,149, for ranging their axes at or about at right angles with 1863, in which a machine having a pair of corrugated those of the pairs of contractile rollers F G, I am not rollers, ,and a pair of plain rollers, is described, all of -only enabled to dispense `vwith the packing-conduit or such rollers being elastic, or made of India rubber or conduits, as used in the machines, as described, in the gntta percha, and used with a trough, and having all United States patents, Nos'.36,005 and 87,806and of their axes parallel, whereby the cloth, in passing thereby much simplify the machine, but operate it through the two pairs, is irst crimped by the corruwith less power, and avoid diffi :i1l'ties incident to' the gated rollers, and afterward has its crimps or corruga-` operations of the said patented machines, and, besides, tions removed by the plain rollers, it thus being preserve all the advantages incident to'them. squeezed in one direction only. I, therefore, claim as my present invention- In my machine, the axes Vot' the crimping or corru- The new or improved machine, as ,set forth, that is, gated squeeze-rollers are disposed at right angles with as constructed, with its main squeezedollers A B cortliose of the plain or 4iiuted rollers, and the cloth, airugated or utedas described, and with one or more ter being crimped by the rollers A B, descends into pairs of rollers, F Gr, arranged Vwith their axes at `or the trough or conduit K, going through the liquor about at right angles with those of the rollersvA B, thereof, and, finally, passes upward over-'the roller H, the whole being as represented and described.

Thus, it will be seen that, by my machine, the cloth will not only be 4crimped. and squeezed in one direction, Witnesses:'

and next be squeezed in a direction at right angles to LYMAN BENNY.
